A girl scout sells 3 boxes of cookies during week 1. She has a goal to sell twice as many cookies each week as she did the week before. If she succeeds in doing this during weeks 2, 3, 4, and 5, how many boxes will she sell all together? a0

If she wants to double the number of cookies she sells, then you just multiply by 2.

Week 1: 3 cookies
Week 2: 6 cookies
Week 3: 12 cookies
Week 4: 24 cookies
Week 5: 48 cookies

3+6+12+24+48 = 93.

All together, she sold 93 cookies.

Hope this helped! :)
